Hey guys, Ive been around here for a while now, Just never really posted any questions, but I cant seem to find the answer to this one...

I have a 2012 doublecab 4x4 Taco and am looking into getting Ext Travel King Coil overs and TC UCA's. I plan to max out the lift as much as I can. 3"? maybe 3.5" if It is capable (DSMS told me 2 3/4" max is all the coilovers can do on a 4x4)

This will obviously put preload and make the ride stiffer. If I go with a 1" longer spring, will it help make a softer ride?

Will it create any complications?

I dont do wheel every weekend. Maybe a couple times a month on sand. I hope to jump with this set up maybe a foot or two in the air or so.

I got some ext kings a few months ago. They come with a 14" 600lb spring. This didn't make sense to me because they compress just to get the adjuster collar on the shock body. With the a arms i had made it lifted it way up. I didn't like it that high so i had them changed to a 12" 600lb spring. This lets me actually adjust using the collar. I say the 12" spring has less chance to bind because it's not compressed to just get it on like the 14". No vibrations out of mine. Driveline issue more than likely.
